8.3.1 ABR Output Message Data
The ABR output messages are written to the 16-bit Holding Registers (40000).
The maximum message size is to 255 registers. This allows for up to 510 8-bit ASCII characters per message. If the
message is longer than 510 characters only the first 510 characters are written, and the rest are discarded. The data is
written in Big Endian format, with the first character of the message written to the upper byte, and the next character written
to the lower byte of the first register. If the message is shorter than the number of registers being written, the ABR writes a 0
value to the extra bytes.
The following table shows the contents of the registers if 255 registers are being written, and the output message is:
[STX]123[ETX]
